To azz whom it may concern:

Be it known that I, J OHN. H. KINEALY, a

citizen of the United States, residing at Ferg l On, in the county of St. Louis and State of Missouri, have invented a new and useful Improvement in Air-Washing Apparatus, of which the following is a full, clear, and exact speclfication, reference being had to the accompanymg drawings, which form a part thereof.

My invention relates to those apparatus by means o fwh1ch air supplied to buildings for ventllatmg purposes is washed by being made to pass through water in the form of thin sheets or finely divided spray. In-these' apparatus the water is made to pass from spray heads through small openings.v The size of these openings depends upon the degreeflof fineness that it is desired shall be given to the spray, but in almost all cases' the size of the openings is such that any dirt that may get into the water is likely to partially clog the o enings so as to render the spray heads ine cient. It is also usual to use the same water over and over agaln, so

that after a short time it becomes very dirty and then the spray heads usually become more or less clogged with dirt, and it becomes necessary to devise some means whereby the spray heads may be flushed at intervals so as to wash out the dirt that may accumulate in them.

The object of my invention is to provide an apparatus for washing air by means of water issuing from spray heads with meansv whereby the spray heads may be automatically flushed and freed of dirt; and a further object of my invention'is to providean air washing apparatus that will need little or no care on the part of an attendant to keep it in an efiicient condition.

My invention is fully shown in the accompanying drawings where similar letters are used to designate similar parts;

Figure 1, shows a side view of the'a'pparatus; Fig. 2, shows a view of that part of the apparatus by means of which the flushing of the spray heads is governed; and Fig. 3, shows a section of one form of spray head which may be used with the apparatus. I

Referring to the figures, A is a spray head connected to the water'pipe B by means of the'short pipe C.

D is a pieceattached tothe member E and which is in contact with the rod 7 of the spray head A. l v

pressure may be brought to bear on the rod f at such times as may be desired.

H is a support carrying a shaft H. A

water panl is connected to the journals J which moveon the shaft H. To the same journals are connected arms K which carry counterweights- L. M is a fork having the prongs m and n.

N is a rod which passes between the prongs of the fork M. and is connected'to the journal O which is'free to move on the shaft H. At the upper end of N there is a weight P. The rod and the weight P constitute a hammer. 1 Y

R is a guide which guides the rod N in its movement and also limits in one direction the extent of the movement of this rod.

S is a sump in' which the water from the spray'head A falls. The relative position ofthe water pan and its various parts wlth respect to the hammer is clearly shown in Figs. 1 and 2. Itwill be. seen from these figures that the hammer is free to move through a limited angle determined by the guide R and-the'strike-piece G, and that by means of the prongs m and n of the fork M, the movement of'the hammer is controlled by the movementof the water pan I.

The construction of the spray head is clearly shown in Fig. 3, where b is the -in-' let, 0 the outlet, and d a tube screwed into the body of the head and provided with a lock-nut e by means of which it can be locked in any. desired position. This tube projects through the outlet and has passing through it a .rod f of smaller diameter than the inside of the tube, This rod f has at tween the nut 70 and the lock-nut. 6 there is a spring 5 which having been lcompressed tends. to expand and thus forces the rod f outward so as to hold the spray plate h in place against the pressure'of the water in the spray head A. The tube d is adjusted so that the spray plate is held at the desired distance from the end of the outlet 0, and then the nut is is adjusted so that the spring 2' exerts sufiicient pressure to hold the rod in place against the pressure exerted on the spray plate by the water. When the rod f is subjected to a pressure that will compress the spring 2', the head of the rod 9 moves away from the outlet 0 and the water issuing from the spray head A forces .the spray plate It to followthe head of the rod so that the opening between the spray plate and the end of the spray head is enlarged and the spray head is flushed so as to wash out any dirt that may have accumulated in the spray head or in, the opening between the outlet 0 and the spray plate h. When the force exerted on f is removed, the spring 5 presses on the nut kand forces the rod fback to its original place and thus carries the spray plate h to its original position in front of the outlet. It is evident that the force brought to bear on the rod fwhereby the spring 2' is compressed and the spray head flushed may be the result of a steady pressure or of a blow.

' The operation of the apparatus is as follows: Water is forced through the pipes 13 and G into the spray head and from there it flows out through the opening between the end of the outlet and the spray plate and is thus converted into a sheet or spray of a greater or less degree of fineness, dependin upon the adjustmentof the spray plate with respect to the outlet 0 and upon' the pressure of the water in the pipes. The air passes through this water and the dirt in the air is washed out and is carried down with the water into the sump S. The frame consisting of the parts D, E, and G is so adjusted and suspended that the piece D is in contact with t e end of the rod f. The water pan is empty and is in the osition shown y the full lines in Fig. 1. The hammer is also as indicated by the full lines in Fig.1. Some of the water issuing from the spray head A falls into the an I and gradually this pan is filled. en it is filled, the weight of the water and the weight of the pan makethe pan tilt downward, as indicated b the dotted lines in Fig. 1, and dump. en the pan begins to tilt the fork M moves with it and the prongm comes in contact with the rod N and movesit until the rod passes beyond the vertical, then the rod and the weight P falls over and the wei ht P strikes the. strike-piece G and moves t e member E and the piece D. Since the piece D is in contact with the rod f of the spray head, force is thus brought on the rod f and the sprin '5 is compressed and the head is flushed. en the pan I has dumped and the water has run out of it into the S, the counterweights L overbalance the pan and make it swing back to its original position shown by the full lines flushed as long as water is made to issue from them.

It is evident that the form and dimensions of the spray head A may be varied without departing from the spirit of the invention, and that the pan I with the shaft H and the counterweights L constitute a motor which may be changed to suit, the requirements of various conditions.

What I claim as new and desire to secure by Letters Patent, is:

1.- In an apparatus for washi air, a plurality of spray heads each provi ed with means whereby it may operated by a blow for simultaneously operating said flushing means, and a motor adapted to cause said blow, substantially as described.

2.
